Requirements

Functions
autoByteFormat(size, decimalPlaces = 2)
Converts from a specified size (in byes) to an equivalent value in byte(s)/KB/MB/GB/TB - uses the most appropriate unit.
See the wiki page for
file size for details on what each of these units are. This function uses the "Binary Measurement" (see the
conversion table for details).
Parameters
size - integer size (in bytes)
decimalPlaces - decimal places to round result. If return is in bytes, no rounding is done, since it's an integer.
ReturnValue
Formatted size in bytes(s)/KB/MB/GB/TB
Format:
if size = 1 (byte)
returns "1 byte"
else if size < 1KB (1024 bytes)
returns "X bytes"
else if size < 1MB (1024 * 1024 bytes)
returns "X KB"
else if size < 1GB (1024 * 1024 * 1024 bytes)
returns "X MB"
else if size < 1TB (1024 * 1024 * 1024 * 1024 bytes)
returns "X GB"
else
returns "X TB"
"X" is the rounded value (to the specified decimal places), in the appropriate units.
Remarks
Size MUST be greater than or equal to zero.
Code
Code:
;converts Size (in bytes) to byte(s)/KB/MB/GB/TB (uses best option)
;decimalPlaces is the number of decimal places to round
autoByteFormat(size, decimalPlaces = 2)
{
static size1 = "KB", size2 = "MB", size3 = "GB", size4 = "TB"
sizeIndex := 0
while (size >= 1024)
{
sizeIndex++
size /= 1024.0
if (sizeIndex = 4)
break
}
return (sizeIndex = 0) ? size " byte" . (size != 1 ? "s" : "")
: round(size, decimalPlaces) . " " . size%sizeIndex%
}
ExampleCode:
1MB := 1024 * 1024
1@26MB := 1.26 * 1024 * 1024
1000@27GB := 1000.27 * 1024 * 1024 * 1024
17@28TB := 17.28 * 1024 * 1024 * 1024 * 1024
